Results show that observer representation of ensembles includes the group's central shape, category ancestor (progenitor), or group mean. Observers also easily reject memory of shapes belonging to different categories, i.e. originating from different ancestors. We conclude that complex categories, like simple visual form ensembles, are represented in terms of statistics including a central object, as well as category boundaries. We refer to the model proposed by Benna and Fusi (bioRxiv 624239, 2019) that memory representation is compressed when related elements are represented by identifying their ancestor and each one's difference from it. We suggest that ensemble mean perception, like category prototype extraction, might reflect employment at different representation levels of an essential, general representation mechanism.There are few reports on the benefits of catheter ablation (CA) in patients with electrical storm (ES). None of these publications included patients with Chagas disease (ChD). Our aims areto analyze (1) all the cases of ES treated with CA and (2) the subgroup of patients with ChD.
Prospective analysis of consecutive patients with ES due to monomorphic ventricular tachycardia (VT) treated with CA.
We included 38 patients 28 males; median age of 63.5 (IQR 55-71) years old; ejection fraction (LVEF) 0.30 (0.25-0.40). Sixteen patients (42.1%) had ChD. The patients experienced 21 (15-37) VT episodes and received 7 (3-13) ICD shocks before CA. Forty-six procedures were performed (7 required epicardial access). All patients experienced ES suppression after CA. After 35 (10-64) months of follow-up (1.21 procedures per patient), 23 patients (60.5%) remain free from any VT; 35 patients (92.1%) were free from ES, and 11 patients (28.9%) died from non-arrhythmic causes. One patient underwent heart transplantation. Patients with ChD were younger (60 vs. 67yearsold; p=?0.033), significantly morewomen (50% vs. 9.1%; p=?0.005), and had higher LVEF (0.40 vs. 0.28; p&lt;?0.001) than the other patients. Long-term outcome of ChD patients was similar to that of the overall population. Only age and LVEF independently predicted mortality.
CA was associated with acute ventricular arrhythmia suppression in all patients with ES. Freedom rates from ES and VT were 92.1% and 60.5% respectively. Despite having a lower-risk clinical profile, patients with ChD had a comparable outcome to that of the other patients.

Patients with history of index PVI for PsAF and scheduled for a repeat ablation procedure for recurrence of the same arrhythmia were enrolled between August 2018 and February 2020. All patients underwent both substrate mappings of the left atrium (LA) with the CARTO 3D map-ping system and with AcM.
Ten patients where included in our analysis. All presented with persistency of PVI in all veins at the moment of repeat procedure. There was no linear relationship in BVM maps between SR and CSd (correlation coefficient 0.31?±?0.15), SR and CSp (0.36?±?0.12) and CSd and CSp (0.43?±?0.10). The % overlap of localized irregular activation (LIA), localized rotational activation (LRA) and Focal (F) regions with LVA was lower at 0.2mV compared to 0.5mV (4.97?±?7.39%, 3.27?±?5.25%, 1.09?±?1.92% and 12.59?±?11.81%, 7.8?±?9.20%, 4.62?±?5.27%). Sensitivity and specificity are not significantly different when comparing composite maps with different LVA cut-offs. AURC was 0.46, 0.48, and 0.39 for LIA, LRA, and Focal, respectively.
Due to wave front direction dependency, LVAs mapped with BVM in sinus rhythm and during coronary sinus pacing only partially overlap in patients with PsAF. LCC-cores mapped during PsAF partially co-localize with LVAs.

The current standard of care for selected patients with PFO and cryptogenic stroke is transcatheter closure, but the risk of post-closure, new-onset atrial fibrillation (AF) is unknown (Vaidya et al., Cardiovasc Diagn Ther. 8(6)739-753, 2018; Kjeld et al., Acta Radiol Open. 7(9)2058460118793922, 2018; Staubach et al., Catheter Cardiovasc Interv. 74(6)889-95, 2009). This systematic review and meta-analysis synthesized evidence on AF development post transcatheter PFO closure and predictors of AF development, and assessed existing knowledge gaps.
Randomized controlled trials and observational studies were selected according to the inclusion criteria of adults that underwent a transcatheter PFO closure without a history of AF. Studies were retrieved from elec between transcatheter PFO closure and incidence of AF.In social interactions, speakers often use their tone of voice ("prosody") to communicate their interpersonal stance to pragmatically mark an ironic intention (e.g., sarcasm). https://www.selleckchem.com/products/gsk2606414.html The neurocognitive effects of prosody as listeners process ironic statements in real time are still poorly understood. In this study, 30 participants judged the friendliness of literal and ironic criticisms and compliments in the absence of context while their electrical brain activity was recorded. Event-related potentials reflecting the uptake of prosodic information were tracked at two time points in the utterance. Prosody robustly modulated P200 and late positivity amplitudes from utterance onset. These early neural responses registered both the speaker's stance (positive/negative) and their intention (literal/ironic). At a later timepoint (You are such a great/horrible cook), P200, N400, and P600 amplitudes were all greater when the critical word valence was congruent with the speaker's vocal stance, suggesting that irony was contextually facilitated by early effects from prosody.
